In the related art, when the main monitoring is down or suspended, the monitoring service cannot continue to monitor normally, and cannot execute the restart function and the related extended functions normally, and the like.
The first embodiment is as follows:
the first embodiment of the present invention provides a monitoring method, the flow of which is shown in fig. 1, including steps S102 to S108:
s102, receiving information of monitored service sent by a monitor;
the synchronization module introduced in this embodiment is a Paxos module, Paxos is a Paxos consistency algorithm, and the synchronization module is used as a middle synchronization component, and can support a module component or an independent service that implements a Paxos consistency protocol, or a distributed application program coordination service zookeeper, etc.
S104, synchronously updating the information of the monitored service to a main monitoring service;
in this embodiment, the monitored service and the monitor are deployed on the same network node, and the network node is a physical machine or a virtual machine. Before receiving the information of the monitored service sent by the monitor, the method further comprises: and receiving a registration request sent by the monitor, and establishing a heartbeat mechanism with the monitor.
The monitor Robot firstly registers itself on the Paxos module in a mode of sending heartbeat messages to the Paxos module, the Poxas module records the monitor Robot, and a heartbeat mechanism is established to complete registration. After registration, the monitor Robot will continuously update its own state on the Paxos module. Meanwhile, the Robot scans all processes of the monitored Service node to find out the monitored Service1, registers the Service information of the Service1 into the Paxos module, and simultaneously the monitor Robot performs a monitoring function on the monitored Service (for example, Service1, Service 2).
S106, receiving a monitoring policy issued by the main monitoring service, wherein the monitoring policy is generated by the main monitoring service according to the information of the monitored service;
in this embodiment, the main monitoring service (Monitor) is responsible for displaying the system status, such as: the life cycle, occupied resources, ports, IO and the like of the monitored service, and the functions of the control system such as monitoring policy management, monitoring policy issuing and management of the monitored service.
S108, sending the monitoring strategy to the monitor, wherein the monitoring strategy is used for instructing the monitor to execute a monitoring command corresponding to the monitoring strategy.
In this embodiment, the monitor Robot is responsible for monitoring a service process, executing a monitoring command, and reporting a state to the Paxos module, where the reporting content is as follows: the life cycle, occupied resources, ports, IO, etc. of the monitored Service, therefore, the monitored Service (Service) needs to be deployed on the same network node as the Robot.
The monitoring method provided by the embodiment improves the high availability of the monitoring system, and the integrated monitoring system has high availability due to the high availability of the Paxos module.
In some scenes, such as after the main monitoring is down, the issued monitoring strategy is not influenced, and the functional state of the monitor is not influenced, so that the monitoring system can continue to monitor the required service and synchronize the information state; after the main monitoring is restarted, the latest monitoring cluster state can be synchronized from the Paxos module. Similarly, the monitor process fails because the heartbeat mechanism is restarted by the master monitor. And if the monitored service is abnormal, the monitor executes a corresponding monitoring command.
Example two:

in this embodiment, the synchronization module is a Paxos module, and after the master monitoring service Monitor is started, the synchronization module synchronizes and monitors information of the Monitor in the Paxos module and information of the monitored service Services monitored by a certain Monitor Robot, and uses the information for statistics and presentation.
S204: generating a monitoring strategy according to the information of the monitored service;
in this embodiment, the main monitoring service Monitor generates a corresponding monitoring policy according to the information of the Monitor and the information of the monitored service Services monitored by a certain Monitor Robot, and the main monitoring service Monitor issues the corresponding monitoring policy to the Paxos module, and then the Paxos module updates the corresponding monitoring policy to the corresponding Robot.
S206: sending the monitoring policy to the synchronization module;
in this embodiment, the main monitoring service Monitor issues the corresponding monitoring policy to the Paxos module of the synchronization module, and then the Paxos module updates the corresponding monitoring policy to the Robot.
S208: and sending a monitoring command corresponding to the monitoring strategy to the monitor.
In this embodiment, the Monitor directly sends the monitoring policy to the Paxos model, and in addition, the monitoring command corresponding to the monitoring policy is directly sent to the corresponding Monitor Robot. For the monitoring strategy, the Robot synchronizes the corresponding monitoring strategy in the Paxos model to the local, and analyzes the monitoring strategy to obtain a monitoring command and execute the monitoring command.
The monitoring method provided by the embodiment overcomes the problem that the monitoring service cannot continue normal monitoring after the main monitoring service is down, and remarkably improves the high availability of the monitoring system.
Example three:
a monitoring method is provided according to a third embodiment of the present invention, fig. 3 is a flow chart of the monitoring method according to the third embodiment of the present invention, as shown in fig. 3,
the monitoring method comprises the following steps:
s302: sending information of the monitored service to a synchronization module;
in this embodiment, the monitor Robot sends the state of the monitored service Services in the flag to the Paxos model service at regular time, where the Paxos model service stores Robot information and monitored service Services information thereof.
S304: synchronously updating the information of the monitored service to a main monitoring service through the synchronization module;
in this embodiment, the main Monitor unit sets a trigger condition according to a specific scene through the Service statistical information obtained by the synchronization module Paxos module, and determines whether to issue the monitoring policy.
S306: receiving, by the synchronization module, a monitoring policy; or receiving a monitoring command which is sent by the main monitoring service and corresponds to the monitoring strategy, wherein the monitoring strategy is generated by the main monitoring service according to the information of the monitored service.
In this embodiment, if a certain monitoring policy is met, for example, after a Service is hung up, a restart command needs to be issued; or a monitoring strategy (as determined by the user by the service) that supports automatic restart. Then, the monitoring command sent by monitor is executed by Robot or the monitoring strategy is synchronized on Paxos, and then the execution is analyzed.
